Data Bar

The Data Bar data visualization displays a 96 by 96 dpi bar image. The colored bar fills the Image top to bottom, while the Value argument determines the amount of colored bar to render to the right of the Zero argument (or to the left in the case of a negative value).

The Minimum and Maximum arguments determine the range of data. The area between the Value argument and the Maximum argument is transparent (or between the Value and the Minimum in the case of a negative value).

Parameters

Select the Use Alternate Color when Value is less than Zero Value check box to enable the Alternate Color parameter. You can use static values or aggregate functions (e.g. Min or Max) to set parameters. For more information on these and other aggregate functions, see the Common Functions topic.

Syntax

=DataBar(Value, Minimum, Maximum, Zero, Color)
=DataBar(Value, Minimum, Maximum, Zero, Color, Alternate Color)

Usage

Use an expression with this syntax in either the BackgroundImage Value property of a TextBox or the Value property of an Image. This renders a bar in the color specified, the length of which changes depending on the number returned by the Value parameter, in the case of the simple example, InStock. If your data contains only positive values, Zero corresponds with Minimum at the left edge of the Data Bar. The area between the Value and the Maximum is transparent.
